For benchmarks, we compare the NN predictions to alternative fast simulation models. Fast approximate simulations [1]}, [2]} save computation time by only integrating tens of time steps, thus are less accurate than the full \(N\) -body simulations. Here we compare the NN model to the popular method COLA (COmoving Lagrangian Acceleration) [1]}, as implemented in L-PICOLA [4]}. COLA solves the particle motions relative to the second order LPT trajectory. We run L-PICOLA with the same settings as the full \(N\) -body simulations, but for only 10 time steps.
